Haliacmon_(mythology)
Haliacmon (or Aliacmon, Ancient Greek: Ἁλιάκμων) was in Greek mythology a son of Oceanus and Thetis. He was a minor river god in his own right, of the eponymous Haliacmon in Macedonia.[1][2] In other mythological traditions he was the son of Palaestinus and grandson of Poseidon.[3] Methone may have been an offspring of Haliacmon.
